The concept was inspired by season four’s finale at the Terminus, where a group of cannibals reside. James Thomlinson, the chef behind London Mess used a mix of veal, beef, pork, chicken liver and bone marrow as the patties for the burgers.

According to Thomlinson, he came up with this recipe based on a description by author William Seabrook, who ate human meat in west Africa and wrote about the experience in his book.
